Tungsten (W) plate is candidate material for divertor. However, its low temperature brittleness can promote damage formation. W laminate, which is fabricated by joining of stacked pure W foils with low temperature ductility, has been developed. In this presentation, development of W laminate using potassium doped W with high recrystallization temperature will be discussed.
