Annealing of Steels When a metal is cold worked (deformed at room temperature), the microstructure becomes severely distorted because of an increased dislocation density resulting from the deformation. Cold working is also referred to as work hardening or strain hardening. As a metal is cold worked, the strength and hardness increase while ductility decreases. Eventually, …
Read MoreBearing Steels The Oxford English Dictionary defines a bearing ‘as a part of a machine that allows one part to rotate or move in contact with another part with as little friction as possible’. Additional functions include the transmission of loads and enabling the accurate location of the components. A bearing is required to sustain …
Read MoreWorkplace Culture Workplace culture is the tacit, (unspoken) social order of an organization, the shared patterns which determine what is viewed as appropriate behaviour of the employees and the group and help the employees make meaning of their collective environment. Its implicit and explicit systems define how an organization works in practice, regardless of what …
Read MoreForging of Carbon and Alloy Steels Forging of carbon (C) and alloy steels constitutes a metal working process, which has the ability to form the material to the desired component shape, while refining the cast structure of the forging material, healing shrinkage voids, and improving the mechanical properties of the material. The amount of subsequent …
Read MoreSteel Castings Steel castings are produced by pouring liquid steel of the desired composition into a mould of the desired configuration and allowing the steel to solidify. The mould material can be silica, zircon, or chromite sand, olivine sand, graphite, metal, or ceramic. The choice of mould material depends on the size, intricacy, dimensional accuracy …
Read MoreImportance of Safety Culture in the Organization The safety culture is a set of practices (ways of doing) and a mindset (ways of thinking) which is widely shared by the members of the organization when it comes to controlling the most significant risks associated with its activities. It is not something which is specific to …
Read MoreCorrosion in Carbon Steels As per ISO 8044:2010, ‘corrosion is the physico-chemical interaction between a metal and its environment, which results in changes in the metal’s properties and which may lead to significant functional impairment of the metal, the environment, or the technical system of which they form a part’. Corrosion is seen when there …
Read MoreCarbon and Low Alloy steel Plates Steel plate is a flat-rolled steel product which is more than 200 mm wide and more than 6.0 mm thick or more than 1,220 mm wide and 5 mm thick. The steel plate rolling mills normally have a working-roll width ranging from 2,000 mm to 5,600 mm. Hence the …
Read MoreManagement of Relationship at Workplace Healthy and positive relationships have been identified as one of the pillars of wellbeing. A healthy relationship can be the most important source of life satisfaction and wellbeing. The quality of relationship at the workplace matters not only for the employees’ ability to flourish personally, but is also likely to …
Read MoreProduction and Characteristics of High Strength Reinforcement Bars During the last few decades, reinforced concrete construction has generally utilized reinforcement bars with yield strength of 415 MPa (415 N/sq mm) for most beams, girders, and columns, and less frequently reinforcement bars with yield strength of 500 MPa for columns which are not a part of …
