摘要： A heat-resistant magnesium alloy is for casting, and includes Ca in an amount of from 1 to 15% by mass, Al in a summed amount of from 4 to 25% by mass with the amount of Ca, and the balance being Mg and inevitable impurities when the entirety is taken as 100% by mass. The heat-resistant magnesium alloy is not only inexpensive, but also effects an advantage that cracks are inhibited from occurring when being cast. For example, a process for producing heat-resistant magnesium alloy cast product includes the step of pressure pouring an alloy molten metal, which has a target composition around Mg-3% Ca-3% Al-from 0.2 to 0.3% Mn, into a cavity of metallic die, which is preheated to a die temperature of from 130 to 140° C. in advance. The process makes it possible to produce die-cast products, which are free from cast cracks.

摘要： A metallic composite material according to the present invention is a metallic composite material, which comprises: a composited portion having a sintered body 1 being completed by sintering a metallic powder of a first metal, and a second metal 2′ infiltrating into the pores of the superficial-layer portion of the sintered body 1 at least; and a parent-material portion having the second metal 2 covering the composited portion, and is characterized in that the sintered body 1 is completed by sintering the metallic powder together with a melt-disappearing material, which possesses a melting point being the sintering temperature of the metallic powder or less, or a burn-disappearing material, which burns to disappear at the sintering temperature or less; and the metallic composite material is equipped with a fitting portion at the interface between the composited portion and the parent-material portion, fitting portion which is formed by infiltrating the second metal 2′ into the pores and additionally getting the second metal 2′ into parts 3 where the melt-disappearing material has been melted to disappear or the burn-disappearing material has been burned to disappear. By means of this novel construction, it is possible to suppress the occurrence of cracks and peeling, which occurs in metallic composite material.In the present invention, the melt-disappearing material can preferably include an alloying component element, which forms an alloy with a major component element of the metallic powder. When major component element is iron and the alloying component element is copper, the strength of the fitting portion improves.

摘要： A magnesium alloy for casting according to the present invention is characterized in that, when the entirety is taken as 100% by mass, it includes copper (Cu) in an amount of from 1% by mass or more to 5% by mass or less, calcium (Ca) in an amount of from 0.1% by mass or more to 5% by mass or less, silver (Ag) in an amount of from 0.1% by mass or more to 5% by mass or less, and the balance comprising magnesium (Mg) and inevitable impurities.By means of including Cu and Ca, crystallized substances of Mg—Ca compounds crystallize in crystalline grain boundaries between Mg crystalline grains as three-dimensionally mesh shapes, along with Mg—Cu compounds. By means of the three-dimensionally mesh constructions, grain-boundary sliding, which becomes active especially when becoming high temperature, is suppressed, and thereby high-temperature strength and creep resistance at high temperature improve. Moreover, by means of the Ag addition, the Mg crystalline grains become micro-fine and thereby the three-dimensionally mesh constructions, whose continuities are high and which are fine, are formed. In addition, it is less likely that Ag affects the heat conductivity of magnesium alloy adversely.
摘要翻译：根据本发明的铸造用镁合金的特征在于，当全部为100质量％时，其包含1质量％以上5质量％以下的铜（Cu），钙（Ca）的量为0.1质量％以上至5质量％以下，银（Ag）的含量为0.1质量％以上且5质量％以下，余量包括镁（Mg）和不可避免的杂质。通过包括Cu和Ca，Mg-Ca化合物的结晶物质与Mg-Cu化合物一起作为三维网格形状在Mg晶粒之间的结晶晶界中结晶。通过三维网状结构，能够抑制特别是在高温时变得活跃的晶界滑动，从而提高高温下的高温强度和耐蠕变性。此外，通过Ag添加，Mg晶粒变得微细，从而形成连续性高且细小的三维网状结构。此外，Ag不太可能不利地影响镁合金的导热性。
