This paper reports the effect of annealing and Equal Channel Angular Pressing (ECAP) on the wear behavior of AA6061 alloy and in situ AA6061-5 wt.%TiB 2 composite. The in situ AA6061-5 wt.%TiB 2 composite was prepared through aluminothermic reduction reaction process using potassium hexafluorotitanate (K 2 TiF 6 ) and potassium tetrafluoroborate (KBF 4 ) salts as precursors in an AA6061 alloy melt. The in situ AA6061-5 wt.%TiB 2 composite and AA6061 alloy were subjected to annealing followed by the ECAP process to refine the grain structure. The wear test was carried out on both the materials (AA6061 alloy and in situ AA6061-5 wt.%TiB 2 composite) in annealed and ECAP processed conditions using steel as a counter face material. The wear testing was carried out for different wear process parameters like load (20, 30 and 40 N), sliding velocity (0.5, 1, and 1.5 m s −1 ) and test...

等通道角挤压下AA6061合金和原位AA6061-TiB 2复合材料的磨损行为

本文报道了退火和等通道角挤压(ECAP)对AA6061合金和原位AA6061-5 wt。%TiB 2复合材料的磨损行为的影响。通过铝热还原反应过程,使用六氟钛酸钾(K 2 TiF 6)和四氟硼酸钾(KBF 4)盐作为前驱体,在A6061合金熔体中制备原位AA6061-5 wt。%TiB 2复合材料。对原位AA6061-5重量%的TiB 2复合材料和AA6061合金进行退火,然后进行ECAP工艺以细化晶粒结构。使用钢作为对面材料,在退火和ECAP处理的条件下,对两种材料(AA6061合金和AA6061-5 wt。%TiB 2复合材料)进行了磨损测试。针对不同的磨损过程参数(例如负载(20、30和40 N),滑动速度(0.5,
