Abstract The refractory tungsten alloys with high ductility/strength/plasticity are highly desirable for a wide range of critical applications. Here we report an interface design strategy that achieves 8.5 mm thick W-0.5 wt. %ZrC alloy plates flexural strength 2.5 GPa and strain 3% at room temperature (RT) ductile-to-brittle transition about 100 °C. tensile is 991 MPa RT 582 500 °C, as well total elongation 1.1% large 41% respectively. In addition, the W-ZrC plate can sustain 3.3 MJ/m 2...
Tungsten is considered as the most promising material for plasma facing components (PFCs) in magnetic confinement fusion devices, due to its high melting temperature, thermal conductivity, low swelling, tritium retention and sputtering yield. However, brittleness, poor machinability strength at high-temperatures of tungsten limits application. Focusing on this issue, various W alloys with enhanced mechanical properties have been developed over recent decades. Among them, W-ZrC exhibit...
W-(0.2, 0.5, 1.0)wt% ZrC alloys with a relative density above 97.5% were fabricated through the spark plasma sintering (SPS) method. The grain size of W-1.0wt% is about 2.7 μm, smaller than that pure W and 0.5)wt% ZrC. results indicated W-ZrC exhibit higher hardness at room temperature, tensile strength high lower ductile to brittle transition temperature (DBTT) W. total elongation W-0.5wt% alloy 700 °C 535 MPa 24.8%, which are respectively 59% 114% those (337 MPa, 11.6%). DBTT materials in...
