Processing arrangement and material model of multi-position progressive stamping The material used for the soleplate component part (as shown in Fig.1) was St52 steel, and the thickness was 2.5 mm; double-row 13 positions progressive strip layout with intermediate carrier was adopted (as shown in Fig.2)[5,6].
The results show that materials at areas A and B bear the tensile stresses; as shown in Fig.13(f), severe thickness thinning and even cracking occur at area B due to the material of area B is located at the gap between the punch and die, and both the deformation degree and work-hardening effect are low; materials at area C and E bear the tensile stress; the first main stresses of area D is the tensile stresses, and the second main stresses of that area is the compressive stresses; wrinkling occurs at area E due to the compressive stress; besides, material at area E bears the compressive stress along the thickness direction due to the blank holder.
(2) For deep drawing of automotive soleplate component part, the materials at the round corners area B connected the top platform and side-wall bear the maximum tensile stresses, severe thickness thinning and even cracking easily occur at area B

Iron and selenium powder were used as raw materials.
The raw materials were milled using a shaker mill for 5 hours after weighed in an atomic ratio of Fe:Se=1.025:1.
Such FeSe-based superconductor investigation followed the discovery of superconductivity of iron-based materials by Kamihara, et al earlier in the same year [2].
To improve the superconductivity of FeSe-based materials, several proven techniques were conducted including substitution and heating with high pressure.
We also thank the Department of Physics Universitas Indonesia and Research Center for Metallurgy and Materials - LIPI for providing us the research facilities.

The effect of different lead frame materials is examined to identify the mechanical characteristics and the different shapes of the lead frame with same SMD type are investigated to distinguish the reliability.
Effect of Lead Frame Materials.
The widely used materials for a lead frame are alloy 42 and Cu alloy featuring different mechanical characteristics summarized in Table 1 which influence the solder joint reliability.

High frequency induction heating is one of the heating sources, which is very effective for conductive materials such as metals.
Materials with green densities below 70.0 % of the theoretical value are not suitable to be effectively sintered via induction heating, especially if high sintering temperatures are sought.
