Research Abstract |
Tungsten fiber reinforced titanium composite (W/Ti composite) wasmanufactured by the spot welding method. Residual stresses in the W/Ti composite was estimated by thehigh temperature in-situ x-ray stress measurement and the cryogenic temperature in-situ neutron stressmeasurement. It was confirmed that the almost generated stresses in the W/Ti composite are the thermalinduced stresses, and depend on the thermal expansion mismatch between the tungsten fiber and thetitanium matrix.
