摘要
本文就挤压温度、挤压速度和挤压比对连续挤压(CONFORM)纯铝管的机械性能和焊合性能的影响进行了研究。结果表明:随挤压温度、挤压轮速和挤压比增加,管材机械性能σ_b和HV_1降低,而延伸率δ％升高;
The effects of the extrusion tomperature, the speed of extrusion wheel and the
extrusion ratio on the mechanical properties, and weld property of pure alumimum
tubes in continuous extrusion (CONFORM) were studied in the paper. The results
show that the mechanical property of aluminum tubes σ_b and HV_1 decreases and
δ% increases and weld property of aluminum tubes improves with the increase
of the extrusion temperature, the spesd of extrusion wheel and extrusion ratio.
