perhaps the most progress has been made with alloys based on nickel and especially titanium aluminides. These alloys can Boron-containing molybdenum silicides have received some exhibit significant room temperature ductility, at least compared interest of late due to their superior low-temperature "pest" to other intermetallics, but have the major disadvantage that their resistance and comparab...

The introduction of computational modelling during alloy development has significantly reduced the cost production and prolonged time spent by researchers doing trials errors in laboratory. In this study, software (JMat Pro) was used to simulate effect addition Zr Co, on material properties NiAl-Mo(Cr) such as elastic modulus, hardness, thermal conductivity, bulk modulus specific heat capacity....

The effects of alloying concentration on the aqueous corrosion behavior aluminum-manganese-molybdenum (Al-Mn-Mo) alloys with 8–20 at% Mn and 0–30 Mo were investigated by experiments atomistic simulations. pitting potential Al-Mn-Mo increased Mo% from − 0.16–0.49 V. passive film thickness depended total alloy concentration, while its compactness defect density individual ones. Specifically, Al80...

This research work aims to study the effect of 2wt%Mo on bainitic transformation kinetics and bainite morphology in 0.6wt%C-1.2wt%Si-1.0wt%Mn-0.2wt%Cr steel. Specimens are austenitized at 950°C rapidly cooled salt bath isothermally treated between 200°C–300°C for different time intervals. Another set specimens oil after an austenitization treatment then tempered temperature range 200°C–550°C. I...

The reaction of Mo(CO)6 with thin films of dehydroxylated alumina grown on a Mo(1 0 0) substrate above 500 K is studied in ultrahigh vacuum using temperature-programmed desorption and Auger and X-ray photoelectron spectroscopies. This results in the formation of a molybdenum carbide that incorporates a small amount of oxygen, where MoC is formed initially, becoming closer to Mo2C as the Mo(CO)6...

Successful implementation of extreme ultraviolet (EUV) lithography depends on research and progress toward minimizing collector optics degradation from intense plasma erosion and debris deposition. Thus studying the surface degradation process and implementing innovative methods, which could enhance the surface chemistry causing the mirrors to suffer less damage, is crucial for this technology ...

There is a competition between several face centered cubic (FCC)-based ordered inter-metallic phases in Ni-Mo alloys containing 8-33 at% Mo. The transformation behavior of these alloys in terms of ordering instabilities has been studied. First-principles tight-binding-linear muffin-tin orbital (TB-LMTO) method coupled with augmented space recursion (ASR) in conjunction with orbital peeling (OP)...

The tensile creep behavior of Cr-Si alloys with Cr ≥ 91 at.% was investigated in air at 980 °C a constant load 50–100 MPa. Additionally, the influence substitutional alloying additions 2 Ge and Mo, leading to ternary studied. addition or Mo results an improvement strength, highest strength achieved Mo. For longer exposure times strong effect is observed, because severe nitrogen uptake from air,...
