A casting apparatus including a die that contains a molten metal that is poured via an opening section disposed above the die. The casting apparatus also includes a heater disposed above the die, and a gas supplying structure for supplying an inter gas to a surface of the molten metal. The casting apparatus further includes a lid disposed between the surface of the molten metal and the heater, and a lid moving structure for moving the lid to the die relatively so as to control the opening amount of the opening section above the die.

Casting apparatus and method therefor

A high strength spongy sintered metal composite sheet comprising a porous spongy sintered metal layer having continuous holes, and a high strength sintered, dense metal reinforcing layer having a porosity smaller than the porosity of the spongy sintered metal layer, laminated thereon, wherein the sintered, dense metal reinforcing layer has a thickness of 0.5-30% thickness with respect to the entire high strength spongy sintered metal composite sheet.

High strength spongy sintered metal composite sheet and production method thereof

An Ni-base heat resistant alloy, has a composition which contains, by weight, Cr: from 12.0 to 14.3%, Co: from 8.5 to 11.0%, Mo: from 1.0 to 3.5%, W: from 3.5 to 6.2%, Ta: from 3.0 to 5.5%, Al: from 3.5 to 4.5%, Ti: from 2.0 to 3.2%, C: from 0.04 to 0.12%, B: from 0.005 to 0.05%, and the balance substantially Ni and inevitable impurities. A large-size casting, as well as a large-size turbine blade, having a columnar crystalline Ni-base heat-resistant alloy formed from the Ni-base heat-resistant alloy, have sound cast surfaces and a sound internal structure.
