美国特种金属公司新开发了一种可时效硬化的高强度镍铁合金“Ｎｉｌｏ ３６５”，是专门作为飞机复合工具材料而研制的。该合金含Ｎｉ４３．５％、其余为Ｆｅ，并通过添加３．３％Ｎｂ和１．４％Ｔｉ来强化，是由于在沉淀硬化处理时形成ｙ‘析出物而强化的。Ｎｉｌｏ３６５合
US specialty metals company newly developed a hardenable high-strength nickel-iron alloy “Nilo 365” that was developed specifically for use as an aircraft composite tool material. This alloy contains 43.5% Ni and the balance Fe, and is strengthened by addition of 3.3% Nb and 1.4% Ti due to the formation of y ’precipitates during precipitation hardening and strengthening.
