The Iron-Carbon Diagram There are two iron-carbon equilibrium diagrams: - stable iron-graphite Fe-Gr - metastable iron-cementite Fe-Fe3C The stable condition usually takes a very long time to develop. The metastable diagram is of more interest. Fe3C iron carbide called cementite because it is hard. Following phases exist on Fe-Fe3C diagram: - liquid solution of iron and carbon (L) - ferrite ( ) – an interstitial solid solution of carbon in Fe (bcc). At room temperature ferrite is ductile but

The concept of order-winners and order-qualifiers is originating from an attempt to explain how internal operational capabilities can lead to competitive advantage‚ market success and answer the following : - What drives customers in buying the products manufactured by a company at all. - What makes customers purchase a certain product instead of a similar one manufactured by a competitor. In order for customers to purchase a product a car for example it needs to meet a set of minimum requirements

ORDER WINNERS AND ORDER QUALIFIERS The operations and supply chain strategy is a functional strategy that indicates how structural and infrastructural elements within the operations and supply chain areas will be acquired and developed to support the overall business strategy. Executing successful operations and supply chain strategies means choosing and implementing the right mix of structural and infrastructural elements. What constitutes the best mix of these structural and infrastructural

Component Diagram Notations The component diagram’s main purpose is to show the structural relationships between the components of a system. In addition‚ component diagrams are useful communication tools for various groups. In creating a component diagram‚ there are different notations that can be used to show the different relationship of each component within the system. The component diagram notation set now makes it one of the easiest UML diagrams to draw: * COMPONENT A component can

USE-CASE DIAGRAM EXERCISE 1. Draw a use case diagram for an ATM machine with the following functionality. A customer’s interaction with the system involves logging in‚ making withdrawal requests‚ deposit requests‚ and balance inquiry requests. If the customer logs in‚ there is a possibility (although rare) that the system will confiscate the card (for example‚ if the login is incorrect or if the bank determines that the customer’s balance is significantly under zero). Card confiscation involves

as Phase Diagrams By _________________ _________________ Material Science Lab #11 Report Introduction The purpose of this lab is to obtain the cooling curves for tin‚ lead and various alloys of these two metals. A phase diagram will be generated from these cooling curves. When a material is heated by adding energy at a constant rate‚ the temperature of the material will increase linearly with time‚ provided a phase transformation does not occur. As temperature of the sample becomes
