特長図1各合金の平均熱膨張係数(1)低熱膨張合金コバールに近い熱膨張係数を有します。
Features Figure 1: Average coefficient of thermal expansionof various alloys(1) Low coefficient of thermal expansion, close to those of Fe-Ni low thermal-expansion alloys.
インバーはそれを知っている's熱膨張係数制御の優れた特性。
Invar is know for it's excellent properties of controlled coefficient of thermal expansion.
As heat expansion coefficient is big, attention should be paid in fitting design such as stress relaxation, decrease in clearance due to temperature change and others.
説明モリブデン銅合金は、調整可能な熱膨張係数と熱伝導率を有するモリブデンと銅との複合材料です。
Description Molybdenum copper alloy is a composite material of molybdenum andcopper which has adjustable thermal expansion coefficient and thermal conductivity.
High temperature molybdenum products like TZM alloys and TZC alloys are widely used due to its high strength,low coefficient of thermal expansion, good conductivity and high corrosion-resistance against molten glass, fused salt and molten metal.
With dilatometers, the coefficient of thermal expansion can be precisely measured; DMA determines the modulus of elasticity and the damping values that are relevant in practice for components.
The coefficient of thermal expansion for urea resin is high and it is known to be a resin with large expansion and contraction. In winter, numerous cracks would start to appear at fixation points.
You can determine the coefficient of thermal expansion, glass and phase transitions as well as polymerization for various samples: liquids, gels, pastes, and certain solids.
The coefficient of thermal expansion is adapted to match that of the high-performance electrolyte based on fully-stabilized zirconium oxide, for example 10ScSZ or 8YSZ.
The uniqueness of Kovar, and thus its importance, is that it has a coefficient of thermal expansion that is remarkably similar to borosilicate glass(hard glass) or ceramic.
MMC(Metal Matrix Composites) is a new material that excels in terms of its density, thermal conductivity,Young's modulus, coefficient of thermal expansion, and strength.
Molybdenum is well suited for glass melting electrodes as it has a high melting point(over 2600℃), extremely high electrical and thermal conductivity,low thermal expansion coefficient and lack of staining when melted with glass.
As special instrumentation components required to meet their non-magnetic,fixed thermal expansion coefficient, high elastic modulus, high electrical conductivity and thermal conductivity and the like;
