Manufacturing technologies are so economically important because they are the means for adding value to raw materials by converting them into useful products. Of the many different manufacturing processes‚ each is well suited to a particular need based on environmental impact‚ dimensional accuracy‚ material properties‚ and the mechanical component’s shape. Engineers select processes‚ identify the machines and tools‚ and monitor production to ensure that the final product meets its specifications

Influence of Heat Treatment on Hardness and Corrosion Resistance of Commercial Aluminium Mayeedul Islam 1‚*‚ S. M. Najmul Hoque2‚ M. Abdullah Al Mahmood2‚ A. A. Shisir 2 ABSTRACT Aluminium and their alloys are widely used as construction materials from house hold appliances to air-craft parts. The commercially pure aluminium has merely low corrosion resistance and hardness compare to aluminium alloy. In this study an attempt has been made to study the influence of heat treatment on the properties

Stress relaxation is an intrinsic property of a material‚ in which‚ the material decreases the applied load held at constant strain with passage of time. The total strain remains constant but a fraction of the elastic strain transforms into plastic strain [3]. Stress relaxation characteristics of a material become vital when designing mechanical fasteners‚ riveted or bolted assemblies‚ shrink or press-fit components‚ solderless electrical connectors‚ etc. Moreover‚ stress relaxation data could be

Silver can be consider as one of the most all-around metals reachable. Indeed silver is a white‚ shiny and soft metal which is often found in its natural form as a mixture with other minerals and metals. Thanks to its properties‚ silver can be consider as a multi-function produce because it can be used in the industrial sector and also as an asset. Indeed‚ silver has a monetary value when paper money is no longer of value. For example‚ in period of inflation or deflation‚ the value of silver can

Benefits Of Choosing Stamped Concrete For Your Patio A plain concrete slab is the typical patio material‚ so if you want something a little more upscale‚ you may start to look at pavers or natural stone. However‚ there’s one option you don’t want to overlook‚ and that’s stamped concrete. It pours on like a concrete slab‚ but it looks just like more expensive stone. Here are some of the benefits of installing a stamped concrete patio. Lower Cost Slate and other stone materials are expensive. They

MATSE 259 Solutions to classwork #8 1. For a 99.65 wt% Fe – 0.35 wt% C alloy at a temperature just below the eutectoid‚ determine the following: (a) The fractions of total ferrite and cementite phase. (b) The fractions of the proeutectoid ferrite and pearlite. (c) The fraction of eutectoid ferrite. (a) This part of the problem is solved by application of the lever rule employing a tie line that extends all the way across the α + Fe3C phase field. Noting that the alloy composition is 99

Utensils are typically tools used within a household. Personally‚ I value utensils as much as I value a penny. However‚ Monica Drake’s analysis of three particular appliances in her rant “Utensils” brings a unique perspective on the value of silverware. While the ordinary fork or spoon doesn’t appeal to Drake’s eyes‚ there are a few specific utensils that have influenced Drake over the years. Drake’s toilet spoon and Victor Hugo spoon are both representations of her past‚ and the divorce fork is
