India’s PM association provides a warm welcome
The President of the Powder Metallurgy Association of India (PMAI), Mr P N S Sivan, gave a welcome address to over 250 delegates at the sixth international conference organised by the PMAI and held in Pune, India. During his speech he traced the history and developments of the PMAI since its conception in 1973, stating that the main focus of the PMAI is to promote powder metallurgy among students, the general public and OEM’s. The association organises short training courses, plant practice sessions, national and international conferences. The size of the PMAI has now grown to 500 life members, he stated.
Conference Chairman, Prof P Ramakrishnan, attributed the success of the previous conferences by the PMAI as the main reason for the current sixth International Conference and Exhibition. He discussed powder metallurgy and particulate materials in detail, stressing the need to focus on cost effective solutions through PM.
Dr Cesar Molins, Director General of AMES SA, Barcelona, Spain and current Vice President and former President of the European Powder Metallurgy Association (EPMA) opened the conference. Dr Molins examined the trends in PM applications and analysed likely changes in technology in the future. He discussed the new markets that are opening up to PM, particularly for hardmetals and tool steels. He illustrated how special alloys and forming technologies have a major impact on living standards such as aviation and medical devices. Even energy mining and oil exploration now have a widened demand, he added.
Mr Hemant Nighojkar, Managing Director, GKN Sinter Metals Pvt. Ltd., Pune, opened the trade exhibition in which 21 companies from India, China, Germany, Sweden, Japan, France, Switzerland and Canada showcased their products and technological innovations in powder metallurgy. The conference had fourteen sponsors and three co-sponsors from India and abroad.
The Annual Fellow of the PMAI award, presented for distinguished services to the PMAI and PM in India, was given to Dr Cesar Molins, AMES SA, Spain, Mr P M Agarwal, SLM Metal P Ltd, a prominent powder producer in India, and to Dr R Sundaresan, posthumously for his invaluable contributions to PM and the PMAI.
The PMAI presented the ‘Best Product’ award to GKN Sinter Metals Pvt. Ltd., Pune, for their ‘Gas Tight Main Bearing’ for use in a rotary compressor. The component was displayed at the GKN stand in the exhibition, allowing delegates a better view of this innovative product.
The paper entitled “Effect of Dilution by iron on sintered properties of M3/2” by J Surywanshi, A Manwatkar and N B Dhokey of the College of Engineering Pune, India, won the award for ‘Best Student Paper’ related to industrial research.
Technical sessions – Day 1
The plenary session of the three day conference began with a presentation by Mr S R Sundaram, Pricol Ltd., India, who reviewed the global PM market and suggested that future trends would be towards achieving high density and high performance components.
The session continued with a presentation by Mr N Nagarjuna, Höganäs AB, Sweden, who considered high strength, light weight, low friction and cost effectiveness as future requirements of auto Components. Mr Jose Correa Neto of Metaldyne, USA, then explained the factors that lead to increasing usage of sinter forged connecting rods in automobiles and other new higher strength materials.
A presentation from Tata Motors, India’s largest auto manufacturer and owner of Jaguar and Land Rover, was given by Mr Sudhir Panse, who discussed how OEM’s can utilise the untapped potential of PM. Panse revealed various PM components that are currently used and components and their production technologies that are going to be used in the future.
Dr Henning Zoz, Zoz GmbH, Germany, illustrated a plethora of wide ranging particulate materials developed by Zoz group such as Zentallium® an Al-base composite material with mechanical properties similar to common steel, nano structured H2-storage solid state materials and systems, phosphate based Li-Ion Batteries (ZoLiBat®) which are expected to be used in the first H2-driven vehicles (H2-Isigo®) in early April 2011.
Presentations by Mr Edul Daver, ACuPowder LLC, USA, Mr S N Desmukh, NTB Hightech Ceramics, Pune, Mr N Chandrachud, GKN Sinter Metals Pvt. Ltd. Pune, Dr S Ashok, Höganäs India, Mr Venkata Subramanian of Nathan and Nathan consultancy pvt. Ltd, Dr Anders Flodin, Höganäs AB, Sweden, Mr Eckart Schneider Höganäs AB, Sweden, Ms Laetitia Brun, Höganäs AB, Sweden and Mr N Chandrachud, GKN Sinter Metals Pvt. Ltd., Pune, completed Thursday’s technical programme.
The first day ended with a cultural programme and dinner at the scenic Aquarius resort on the banks of Khadakvasla Lake. Delegates were entertained with a traditional Lavani folk dance performed by dancers from Maharashtra. The mood and tone to relax soon followed and the delegates joined in the festivities and ‘shook a leg’ to Bollywood music!
Technical sessions – Day 2
Friday’s plenary session (4th February) was opened by Mr Jerome Sabathier, Ochio Imaging Solutions, France, who explained the importance of image analysis in studying particle size shape and morphology. Dr Sanjay Basu, Sandvik Asia Ltd, Pune, delivered the R V Tamhankar memorial lecture about how the R&D laboratories at Pune have become a global PM R&D hub for hard materials and powders.
Dr G J Prasad, Bhabha Atomic Research Center, Mumbai, as part of P R Roy memorial lecture, discussed the processing of metallic, ceramic and composite fuels for different types of nuclear reactors built in India. The S L N Acharyulu memorial award lecture, newly established by the International Advanced Research for Powder Metallurgy and New Materials (ARCI) in Hyderabad, was given by Dr G Malakondaiah, Director, Defence Metallurgical Research Laboratories (DMRL), Hyderabad, on strategic applications developed at DMRL using powder metallurgy.
Mr N Gopinath, Fluidtherm Technology P. Ltd, Chennai, discussed developments in energy efficient furnaces for high temperature sintering, sinter hardening, rapid quenching and steam treatment with emphasis on cost reduction.
