Abstract: Methods and apparatuses for stabilizing the strain-temperature response for a shape memory alloy are provided. To perform stabilization of a second sample of the shape memory alloy, a first sample of the shape memory alloy is selected for isobaric treatment and the second sample is selected for isothermal treatment. When applying the isobaric treatment to the first sample, a constant stress is applied to the first sample. Temperature is also cycled from a minimum temperature to a maximum temperature until a strain on the first sample stabilizes. Once the strain on the first sample stabilizes, the isothermal treatment is performed on the second sample. During isothermal treatment, different levels of stress on the second sample are applied until a strain on the second sample matches the stabilized strain on the first sample.

Abstract: A tool steel production method and a tool steel are disclosed in this invention. The method consists of following two steps:1. Toughness (Ch) of the tool steel is evaluated from a formula:Ch=f(Vp, H, T)after estimating Vp, a square sum of output voltage of total Barkhausen noise signals which are produced in the process of magnetization of the tool steel sample, and measuring temperring hardness (H) and hardening temperature (T) of the tool steel sample.2. A tool steel having a required toughness is produced by adjusting temperring hardness (H) and/or hardening temperature (T) based on the toughness evaluation of the tool steel sample mentioned above.
