Abstract
In this paper, shear localization due to strain softening in sidepressed cylinders, is inverstigated. Shear localization causes formation of macroscopic shear bands which can be obsserved in the metallographic cross-section. In this paper, for the first time a method is presented in which a simple two-slice model is used to study the formation of shear bands. The results obtained form this model are in perfect agreement with the results obtatained form experimental works for and micrcrostructures in Ti-6242Si alloy.

Abstract
In this research, Ti-6Al-4V alloy was brazed with 410 stainless steel by three different filler metals as silver-base,
nickel-base, and titanium-base alloys. In order to obtain optimum clearance, brazing was done in three different clearances
of 0.02, 0.04 and 0.06 mm. Also, the strength and hardness of the brazing zone were investigated. The results of shear strength
showed that the brazed samples with titanium-base alloy at the clearance of 0.02 mm had the maximum strength among the
different samples which was 149.5 MPa.

Abstract
In this paper, in order to study the flow behavior and elongation of as-cast ingots of SP-700 titanium alloy, hot tensile test was done in α/β dual phase and β single phase regions using strain rate of 0.1 s-1. Results showed that the hot tensile behavior of SP-700 in the α/β dual phase region (700-900 ºC) was different from the β single phase one (950-1100 ºC) due to the nature of alpha and beta phases and their crystallographic structure. This was since the number of slip systems and deformation mechanism in HCP structure were different from those in BCC structure. Beside, the intensive variation of elongation in microstructural studies showed that the dominant mechanism of hot tensile deformation of SP-700 alloy was dynamic recovery (DRV). Thus, serration of grain boundaries and occurrence of DRV were the reasons for the increase of elongation with the rise of temperature. However, beta grains growth and occurrence of grain boundary fracture made a slight decrease in elongation in the temperature range of 1000-1100 ºC.
