摘要

研究了SiC含量和热处理工艺对C194合金组织与性能的影响。结果表明

冷轧压下量为85%时

经过375℃×2h时效处理后合金的综合性能良好。添加0.6%的SiC时效处理后合金的抗拉强度为339.03MPa

比未添加SiC的时效后的C194合金提高了7.7%

且保持较好的导电性能。同时

SiC能强化时效效果

未添加SiC的合金试样冷轧后直接进行时效处理

其抗拉强度比冷轧后的合金试样提高了0.41%;添加SiC并冷轧后时效的合金

其平均抗拉强度为338.78MPa

比冷轧合金的抗拉强度平均提高了6.14%。

Abstract

Effects of heat treatment and SiC content on microstructure and mechanical properties of C194 alloy were investigated.The results show that the desirable comprehensive properties of the alloy can be obtained with cold rolling reduction of 85% and aging treatment at 375 ℃for 2h.The tensile strength of the alloy with 0.6% SiC reaches 339.03 MPa after aging treatment

increased by 7.7%than the C194 alloy without SiC after aging treatment

and the satisfied electrical conductivity is retained.Compared with the cold rolling alloy without SiC addition

tensile strength of the alloy with aging treatment after cold rolling reaches 313.6 MPa

only increased by 0.41%

while the tensile strength of the alloy with SiC reaches 338.78 MPa

increased by 6.14%.
