Abstract

High heat load tests are conducted on tungsten (W) using two different heat sources. W, when applied in bulk material form, is used above the ductile brittle transition temperature (DBTT) but below about 1500 °C to avoid recrystallization. Bulk W can be used as a thin tile or deposited film on some structure materials. The thermal expansion coefficient of W is small. Brazing of W to heat sink materials results in cracking due to the large thermal stress.
