Origin of Non-metallic Inclusions in Steel Produced during Pit Practice Process

non-linear study of various slit shear walls in steel structures

seismic retrofit strategies have been developed in the past few decades following the introduction of new seismic provisions and the availability of advanced materials and methods. it can be observed that new approaches to deal with more lateral forces are more innovative and more energy absorbent. in line with this, there is a growing trend toward the use of steel shear walls as a system with ...

Parameter Sensitivity Analysis of Pit Initiation at Single Sulfide Inclusions in Stainless Steel

Sensitivity analysis methods were used in conjunction with a mathematical model for corrosion pit initiation in the vicinity of MnS inclusions in stainless steel to investigate the relationship between physicochemical parameters and the potential and concentration distributions. The finite difference method with central differences was used to calculate sensitivities. The mathematical model of ...

Study of Non - Metallic Inclusions in Alloy 825 Hans

Analytical, Experimental and Finite Element Investigation of Internal Pressure Effect in Hydroforming Process on Metallic Bellows Produced from Thin Wall Tube of Austenitic Stainless Steel Grade 316L

One of the bellows producing method is hydroforming process .Whereas some factor of hydroforming process specially internal pressure affects on final characteristics produced bellows such as bursting, wrinkling and wall thickness distribution. In this paper the effect of internal pressure factor in final quality of produced bellows will be investigated. In simulation of process, ABAQUS/Explicit...

Inclusion Evolution during Modification of Alumina Inclusions by Calcium in Liquid Steel and Deformation during Hot Rolling Process

The production of clean steel involves the controlling, elimination, or modification of nonmetallic inclusions. In Al-killed steels, alumina is the main type of inclusion. Calcium treatment, by wire feeding, is commonly used to modify solid alumina inclusions to calcium aluminates, which exists in a fully or partially liquid phase. Liquid inclusions can improve steel castability, but make inclu...
