High temperature deformation behavior of cast 310S stainless steel has been investigated in this study by performing tensile and compression tests at temperatures from 900 to 1200C. Rectangular ingots of which the dimensions were 350×350×100 in millimeter were cast using vacuum induction melting. Phase equilibrium was calculated using the FactSage®, thermodynamic software and database. Thermal ...

NB-506 is a topoisomerase I (top1) inhibitor in clinical trials. In this study, we used a series of camptothecin (CPT)-resistant cell lines with known top1 alterations. We show that three mutations in different domains of the top1 enzyme that confer CPT resistance also confer crossresistance to NB-506. The CPT-resistant cell lines and corresponding mutations were: human prostate carcinoma cells...

Duplex stainless steels (DSSS) have a microstructure composed of ferrite and austenite phases that gives them a very good combination of mechanical and corrosion properties. These steels are desirable for many applications in the chemical and petrochemical industries. In the present study, a type of stainless steel was cast, solution annealed at 1200°C for 60 min and then quenched in water. Ini...

A study of the ignition of non-fire-resistant hydraulic fluid sprays was conducted by the National Institute for Occupational Safety and Health. Both an open flame and a hot steel surface were used as the external heat sources. With the open flame as the heat source, the minimum oil temperature and minimum spray nozzle pressure that resulted in an ignition were measured. The effects of the dist...

Although delta ferrite is a very common phase in most austenitic stainless steels, studies about its formation and evolution during slab processing from industrial heats of tens tons are scarce. The main objective this research to study the (quantity, chemical composition, morphology, distribution) along production route cast coil an heat 80 304 steel. Samples were extracted after following ste...

Ferritic stainless steels (FSS) develop poor surface finish during processing and this is attributed to the large columnar grains formed solidification. Addition of alloying elements such as Al, Ti Nb used in dual stabilized FSS improve solidification structures. In work, two 441 FSS, with 0.023 0.068 %Al respectively were investigated as-cast condition. The equiaxed zone ratio was determined b...
