A superalloy, or high-performance alloy, is an alloy with the ability to operate at a high fraction of its melting point. [1] Key characteristics of a superalloy include mechanical strength , thermal creep deformation resistance, surface stability, and corrosion and oxidation resistance.

高温合金是指以铁、镍、钴为基，能在600℃以上的高温及一定应力作用下长期工作的一类金属材料，具有优异的高温强度，良好的抗氧化和抗热腐蚀性能，良好的疲劳性能、断裂韧性等综合性能，又被称为“超合金，”主要应用于航空航天领域和能源领域。

2021年5月11日 · In this article, I will mostly focus on the most common type of superalloy, the nickel-based superalloy with a gamma-prime microstructure. This article is a basic introduction to superalloys and I’ll explain relevant metallurgy concepts along the way.

高温合金，又稱热强合金、超级合金（superalloy），是指能在高温環境及一定應力作用下長期工作的一類金屬材料，具有良好的抗高溫氧化和抗熱腐蝕性能，以及優異的高温強度、疲勞強度、蠕變 斷裂韌性等綜合性能。

2021年1月1日 · The superalloy ingot is positioned in a furnace and then cogged or forged upon removal from the furnace. Primarily the ingot deforms many times along its length at various points. The applied deformation causes significant recrystallization to a structure of finer grain, and the entire process is repeated after re-heating [73] , [74] , [75 ...

The thermal conductivity of superalloy – Inconel 718 is 6.5 W/(m.K). The heat transfer characteristics of a solid material are measured by a property called the thermal conductivity , k (or λ), measured in W/m.K .

The most important type of superalloy is the nickel-based material that contains a high concentration of chromium, iron, titanium, cobalt and other alloying elements. Nickel superalloys can operate for long periods of time at temperatures of 800–1000 °C, which makes them suitable for the hottest sections of gas turbine engines.

4 天之前 · This superalloy can withstand some enormous pressure. Superalloys are must-need materials for building things that need to operate under intense mechanical and thermal stress, like military ...

A superalloy, or high-performance alloy, is an alloy usually based on Group VIII A elements that exhibits excellent long-time strength, creep resistance, corrosion and erosion at temperatures above 1200 o F, good surface stability, and corrosion and oxidation

2023年3月30日 · They are often more well-developed than metal-cutting methods for superalloys. In other words, paying a skilled laborer to spend hours lining a piece of mild steel with welded beads of superalloy is more economical than buying a plate of superalloys outright.
