The effect of alloying Cr-rich Cr-Si alloys with Pt was investigated by a combination of complementary experimental methods and atomic scale modelling. The investigated Cr-Si and Cr-Si-Pt (Cr ⩾86 at.%) alloys developed a two-phase microstructure co

Due to the inhibiting behavior of Cu, NiCu alloys represent an interesting candidate in carburizing atmospheres. However, manufacturing by conventional casting is limited. It is important to know whether the corrosion behavior of conventionally and a

Some alloys such as many Cr-based systems show mass gain discontinuities during thermogravimetric measurements which strongly affect the oxidation kinetics. The behaviour cannot be described by the current models available in the literature. Thus, a

The tensile creep behavior of Cr-Si alloys with Cr ≥ 91 at.% was investigated in air at 980 °C with a constant load of 50–100 MPa. Additionally, the influence of substitutional alloying additions of 2 at.% Ge and Mo, leading to ternary alloys wa

To reduce scale spallation, scale volatilization, and nitrogen embrittlement in Cr-based systems, reactive elements such as Y, Zr, Hf, La, and Ce were introduced as oxide dispersions into pure chromium. In addition, Hf coating systems were investigat

The microstructural development of Cr Si alloys with Cr ≥ 89 at.% has been studied. As well as silicon, up to 2 at.% germanium, molybdenum, and platinum were used as alloying elements. All alloys consist of only two phases, Crss and A15. The phase

A comparative study on the isothermal oxidation behaviour of the two β0–containing titanium aluminide alloys GE 4822 and TNM-B1 in the HIPed condition has been conducted at temperatures between 600 °C and 900 °C for up to 1000 h in air. The two

Refractory metals are promising materials for high-temperature applications. However, these materials exhibit low oxidation resistance at elevated temperatures. To overcome this problem, aluminum diffusion layers were applied to molybdenum, niobium,

Cr-Si-based alloys are promising candidates for high temperature materials which can resist temperatures beyond the commonly used Ni-based superalloys (> 1150°C). Thereby, higher working temperatures can be used in high temperature applications, whi
