hardening alloy sentence in Hindi

Examples

1. When very large amounts of solutes are added, alloy steels may behave like precipitation hardening alloys, which do not soften at all during tempering.
2. Examples of precipitation hardening alloys include 2000 series, 6000 series, and 7000 series aluminium alloy, as well as some superalloys and some stainless steels.
3. Unlike steel, in which the solid solution separates into different crystal phases ( carbide and ferrite ), precipitation hardening alloys form different phases within the same crystal.
4. Although most precipitation hardening alloys will harden at room temperature, some will only harden at elevated temperatures and, in others, the process can be sped up by aging at elevated temperatures.
5. While the high strength of steel results when diffusion and precipitation is prevented ( forming martinsite ), most heat-treatable alloys are precipitation hardening alloys, that depend on the diffusion of alloying elements to achieve their strength.
6. Higher tempering temperatures tend to produce a greater reduction in the hardness, sacrificing some yield strength and tensile strength for an increase in precipitation hardening alloys, which produces the opposite effects under the conditions found in quenching and tempering, and are referred to as maraging steels.
