The dimensions of steel
نویسنده
چکیده
There are important aspects of steel which are hidden from ordinary view and largely from the users of steels. They nevertheless determine the macroscopic behaviour. One example is that the magnetic properties of austenite determine that it has a larger thermal expansion coefficient than ferrite, whereas intuition would suggest otherwise given that austenite has a greater density. This and other aspects of the physical and descriptive dimensions of steel are described in this paper.

متن کاملThe predictive power of injuries reporting rate and its dimensions by fatalism among the workers of a steel company
Background: Fatalism, an obstacle to the adoption of safe behaviors, describes the belief that injuries are unavoidable and occur due to haphazard or fate. The present study examined degree of fatalism related to injuries reporting rate and its dimensions among workers’ Isfahan Steel Company. Methods: A self-administered anonymous was distributed to 250 workers. The survey included demogr...
متن کاملMATHEMATICAL AND TECHNICAL OPTIMA IN THE DESIGN OF WELDED STEEL SHELL STRUCTURES
In some cases the optimum is the minimum of the objective function (mathematical optimum), but in other cases the optimum is given by a technical constraint (technical optimum). The present paper shows the both types in two problems. The first problem is to find the optimum dimensions of a ring-stiffened circular cylindrical shell subject to external pressure, which minimize the structural cost...
