Effects of sintered commercial Kovar/spl trade/ alloys with controlled powder size and porosity on the corresponding mechanical properties were investigated in the present study. Experiments showed that the sintered alloys have lower coefficient of thermal expansion compared to the conventional casting ones. Porosity of the sintered alloys could dominate(More)
A Taylor-type crystalline plasticity model, implemented into the commercial finite element analysis software, is coded as a subroutine to investigate the behavior of a stainless steel sheet with a body centered cubic (BCC) structure in the current study. Thickness variations of the sheet are examined under the micro-groove formation procedures. Effects of(More)
