چکیده
Abstract. The excellent performance of duplex and super stainless steels due to their high corrosion resistance mechanical strength is directly related austeno-ferritic microstructure. However, these may suffer the formation secondary brittle phases when they reach temperatures between 600°C 950°C causing catastrophic service failure components. In order understand influence history steel, equal channel angular pressing was applied on UNS S32750 bar samples. ECAP processed by using a hydraulic press (DE-80). Microstructural characterization carried out severe plastic deformed samples means OM, SEM EBSD. Ultimate tensile has improved with low decreasing elongation after first pass. process resulted produce faster precipitation if compared non-ECAP

Effect of Thermomechanical Processing on the Microstructure and Mechanical Properties of a Duplex Stainless Steel
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...
متن کاملTHE EFFECT OF SEVERE PLASTIC DEFORMATION ON THE MICROSTRUCTURE AND MECHANICAL PROPERTIES OF AS-CAST AZ31
The evolution of microstructure and mechanical properties of a magnesium cast alloy (AZ31) processed by equal channel angular pressing (ECAP) at two different temperatures were investigated. The as-cast alloy with an average grain size of 360 was significantly refined to about 5 after four ECAP passes at 543 K. Grain refinement was achieved through dynamic recrystallization (DRX) du...
متن کاملInvestigation of microstructure and mechanical properties of low carbon steel sheets after severe plastic deformation in corrugation dies
Recently, bulk nano-structured materials produced by severe plastic deformation (SPD) have attracted scientists attention. Materials produced by SPD are of great importance because of (1) non-porous structure, (2) great mechanical properties such as high strength and toughness and (3) proper dimension for mechanical and physical testing. Several methods have been introduced for imposing the s...
متن کاملMICROSTRUCTURE AND MECHANICAL PROPERTIES OF THE ULTRAFINE-GRAINED COPPER TUBE PRODUCED BY SEVERE PLASTIC DEFORMATION
In this paper, cyclic flaring and sinking (CFS) as a new severe plastic deformation (SPD) method was employed to produce the ultrafine grain (UFG) copper tubes. The extra friction has eliminated in the CFS method that provided the possibility for production of longer UFG tubes compared to the other SPD methods. This process was done periodically to apply more strain and consequently finer grain...
متن کاملInfluence of Initial Microstructure on Hot Deformation Behavior of Duplex Stainless Steels
In this research the effect of initial microstructure on hot deformation behavior in terms of Ferrite-to-Austenite ratios is studied. Two types of stainless steels C1 and C2 were homogenizing heat-treated and deformed under hot compression examinations at temperatures 900ºC and 1100ºC at strain rate of 0.1s-1. The results showed that the flow stress levels of specimens are strongly r...
