Y alloy is a nickel-containing aluminium alloy. It was developed by the British National Physical Laboratory during World War I , [ 1 ] in an attempt to find an aluminium alloy that would retain its strength at high temperatures.

Y alloy (4% copper, nickel, magnesium) Aluminium also forms complex metallic alloys, like β–Al–Mg, ξ'–Al–Pd–Mn, and T–Al 3 Mn.

Y alloy is a nickel -containing aluminium alloy. It was developed by the British National Physical Laboratory during World War I, in an attempt to find an aluminium alloy that would retain its strength at high temperatures. Duralumin, an aluminium alloy containing 4% copper was already known at this time.

Such a material was developed from a forging alloy known widely as RR58 (2618) which itself had been adapted from an early casting alloy (Al–4Cu–1.5Mg–2Ni) known originally in England as Y alloy.

By the end of the First World War an aluminium alloy called ‘Y alloy’ — created by Dr Walter Rosenhain, a metallurgist at the National Physical Laboratory — proved significant in the production of aero-engine pistons.

An alloy is a mixture of chemical elements of which in most cases at least one is a metallic element, although it is also sometimes used for mixtures of elements; herein only metallic alloys are described. Metallic alloys often have properties that differ from those of the pure elements from which they are made.

Y-Alloy is also called copper-aluminium alloy. The addition of copper to pure aluminium increases its strength and machinability. Its composition contains following chemical contents.

Sep 12, 2023 · This study investigates the mechanical characteristics of extruded Mg–0.8 wt% Y alloy, focusing on the effects of yttrium (Y) content, texture intensity (TI), grain size, and loading. Crystal plasticity finite element (CPFE) modeling is employed to analyze the Mg–0.8 wt% Y …

In this paper the development of a new y'/ Y'-alloy on the basis of Alloy718 is presented, where the microstructure is stable at 800°C, mechanical properties are similar to Alloy718, yet do not deteriorate beyond 650°C, and the forging window is wider than the one of

Aug 11, 2019 · This is an alloy of 4% Cu, 1.5% Mn, 2% Ni, 6% Si, Mg, Fe and the rest is Al. It gives large strength at high temperatures. It is used for aircraft engine parts such as cylinder heads, piston, etc
