【摘要】 在常规摩擦焊接参数确定的条件下,研究了顶刹时差和顶锻速度对NiCr20TiAl/4Cr10Si2Mo摩擦焊接面形变的影响。发现当顶刹时差为0.3s,顶锻速度为30 mm/s时,能形成交织状的摩擦焊接面,从而找到了提高异种高强金属摩擦焊接头强韧性能的新途径。更多还原

【Abstract】 Under the condition of certain conventional friction welding parameters, the effects of braking time difference and upsetting rate on deforma-tion of NiCr20TiAl/4Cr10Si2Mo friction welding inter-face are studied. It is found when braking time differ-ence is 0.3s, and upsetting rate is 30mm/s, interlaced friction welding interface is formed, therefore, a new way to improve the tenacity of dissimilar high strength metal friction welding joint is found.更多还原
