Shape effect of ultrafine-grained structure on static fracture toughness in low-alloy steel.
A 0.4C-2Si-1Cr-1Mo steel with an ultrafine elongated grain (UFEG) structure and an ultrafine equiaxed grain (UFG) structure was fabricated by multipass caliber rolling at 773 K and subsequent annealing at 973 K. A static three-point bending test was conducted at ambient temperature and at 77 K. The strength-toughness balance of the developed steels was markedly better than that of conventionall...
متن کاملImprovement In The Corrosion Rate And Mechanical Properties Of Low Carbon Steel Through Deep Cryogenic Treatment
Exploration of the benefit of cryotreatment for achieving improvement in corros ion rate of mild steel is a topic of current research interest. This study is concerned with the effect of deep cryogenic treatment at temperature of -193 0 C on the corrosion rate and mechanical properties. A series of corrosion rate tests have been carried out to cryotreated samples. The specimen were divided into...
متن کاملGeneralized Fracture Toughness and Compressive Strength of Sustainable Concrete Including Low Calcium Fly Ash
The paper presents the results of tests on the effect of the low calcium fly ash (LCFA) addition, in the amounts of: 0% (LCFA-00), 20% (LCFA-20) and 30% (LCFA-30) by weight of cement, on fracture processes in structural concretes. In the course of the experiments, compressive strength of concrete and fracture toughness for: I (tensile), II (in-plane shear) and III (anti-plane shear) models of c...
متن کاملLOW INTENSITY PULSED ULTRASOUND TREATMENT INCREASES RABBIT RADIAL FRACTURE HEALING
In order to study the effect of ultrasound (US) on bone healing, a complete transverse fracture was made in the right radius of adult male rabbits by a cutter. 52 rabbits were used: group I. control (n= 17): group 2. test (n:=: 15): group 3, intact (n= I) and group 4 (n= 12) who were examined only for evaluation of the cutter effects in detail. 7 animals were operated with a Gigli saw. The ...
متن کاملLow Voltage Ride-Through Capability Improvement of Doubly Fed Induction Generator using DVR and SMES
Abstract: With the growth of communities and the increasing need for electricity, and because of the many benefits of renewable energy sources, the wind turbine has become a completely commercial and inevitable process, with increasing penetration into the electricity grid. Distribution networks, on the other hand, are subject to fault that cause power fluctuations and outflow of wind units. In...
