ON THE COMBINED EFFECT OF LUBRICATION AND COMPACTION TEMPERATURE ON PROPERTIES OF IRON-BASED P/M PARTS
Addition of lubricant in the form of admixed with powder reduces friction between die wall and powder during compaction of P/M parts. However, it has detrimental effect on mechanical properties. On the other hand, warm compaction of powders improves...
A Genetic Approach to the Synthesis of Combinational Circuits with Optimum Area and Speed
: In this paper, a software technique for the design of combinational digital circuits with minimum silicon surface allocation and gate propagation delay using genetic algorithm is presented. In existing methods which use ...
Texture Evolution of Ultra-Fine Grained Commercially Pure Copper Produced by Multiple Compressions in a Channel Die
In the present study, commercially pure copper was subjected to multiple compressions in a channel die in
which the specimen undergoes plain strain deformation during each pass. The specimen geometry and
height reduction during each...
Numerical Simualtion of a Non-Newtonian Fluid during the Filling Process of a Die
In this paper, a numerical model is developed which can predict behavior of non-Newtonian fluids.
Enhanced superplasticity in AA2024 aluminium alloy processed by multiple compressions in a channel die
Superplasticity of AA2024 aluminium alloy processed by multiple compressions in a channel die was investigated by impression testing in the temperature range of 613-703 K. The values of strain rate sensitivity parameter of 0.49-0.56 and activation...
