PROPRIETARY ATI 17-7 热处理
- To develop the high precipitation hardened strength of the alloy by heat treatment, starting from Condition A, heat treatments are done to accomplish two necessary steps. The first is a heat treatment which allows the relatively stable austenite of Condition A to transform to martensite (Austenite Conditioning and Transformation). The second is a precipitation hardening heat treatment to further strengthen the material. The austenite is easier to transform to martensite using a lower temperature heat treatment. For this reason, Condition TH 1050 uses a 760°C (1400°F) heat treatment to produce a martensite transformation around room temperature, and this is followed by a precipitation hardening heat treatment at 565°C (1050°F). If Condition RH 950 is desired, the austenite conditioning heat treatment is conducted at 955°C (1750°F). In this case, the martensite transformation is not complete until the material is held for some time at -73°C (-100°F). When the transformation is complete, the material is precipitation hardened at 510°C (950°F) to Condition RH 950.
When alloy with an austenitic structure is cold worked by substantial deformation, a transformation to martensitic structure results from the deformation. In this condition, Condition C, the material may be precipitation hardened directly by heat treatment at 482°C (900°F) to condition CH 900.
