Neutron strain scanning was employed to investigate the internal stress fields in steel plate coupons with embedded prestrained super- elastic NiTi shape memory alloy inserts. It is shown that if the NiTi inserts are embedded into the elastic steel matrix following a carefully designed technological procedure, the internal stress fields vary with temperature in a reproducible and predictable way. It is estimated that this mechanism of internal stress generation can be safely applied in the temperature range from -20C to 150C and is relatively resistant to thermal and mechanical fatigue.
