To give a better understanding of the materials selected for the investigation, the features and general purposes/uses of the alloys are described below:

 

 

2343

 

Variations of this alloy are often used in the die casting industry as the material selected for the high stressed moulds. It shows long life toughness characteristics in all orientations, performs well at high temperatures and has a very fine grain structure.

 

 

 

832

 

This alloy is commonly used in low cost, sheathed heater applications. Its aesthetic properties make it suitable for domestic use and it exhibits good thermal stability and resistance to pitting. Its formability and weldability make it a popular choice for “high output continuous strip welding.” It is also used in other domestic applications such as furniture and screws.

 

 

 

Inconel 617

 

This nickel based‘super-alloy’ (that being an alloy which has several key characteristics) shows great oxidation resistance as well as maintain strength when subject to high temperatures. The ability to retain its properties at high temperatures means that this alloy is often used within combustion chambers of both aircraft and gas turbines and also for components in both fossil fuel and nuclear power plants.

 

 

 

R350

 

This alloy also has found a common use in gas turbine compressors and its high strength and resistance to corrosion means that it is also the material selected to be used for industrial cutters.

 

 

 

Nikrothal

 

This nickel-chromium alloy is often used where temperatures above 1200°C are present. Its high resistivity along with its resistance to oxidisation makes it an ideal material to be used in electrical resistors and heating elements. Other features of the alloy include good ductility and weldability.

 

 

 

353

 

This alloy has a higher nickel content than most stainless steels. For temperatures of 1150°C the material is no longer within its serviceable range. It tends to be used for components requiring creep resistance and heat resistance in the engineering industry, particular in the cement industry and within energy conservation plants.

 

 

254

 

The main features of the 254 alloy is its ability for be fabricated and its high upper service temperature limit. The toughness and oxidation resistance make it ideal for uses within furnaces and also in petrochemical plants
