摘要：
The results of investigations of phase composition, crystal structure and martensitic-transformation (MT) characteristics in quenched alloys of Cu- Al-Co system with 14-17 wt.% Al and 2.5-7.5 wt.% Co are presented. As revealed, in quenched alloys during their cooling, the MT occurs. The dependence of MT characteristics on cobalt and aluminium concentrations in P-solid solution is determined. As shown, the increase of amount of the precipitated CoAl phase for 1% leads to reduction in M-8 on 50 degrees C.
