Desribe the general composition, properties, uses, applications of the following materials and their reasons:
- HSLA steel
- Gray cast iron
Expert Solution

Step 1
1) HSLA steel stands for High-strength low-alloy steel
Composition : low carbon content of between 0.05% – 0.25% for sufficient formability and weldability and the remainder iron.
and a manganese content of up to 2%
Properties : 1) HSLA has high strength to weight ratio.
2) High resistance against temperature
3) High resistance against corrosion
4) formability
5) weldability
6) Resistant to fatigue etc

Step 2
Uses : 1)Used in bridges or buildings for weight saving and durability
2) Most of the Automobile materials are made from it
Applications : HSLA are designed to handle large amounts of stress or need a good strength-to-weight ratio. HSLA steel cross-sections and structures are usually 20 to 30% lighter than a carbon steel with the same strength and hence are used in constructions and automobile industry very frequently

Identify the following polymer processing techniques as either: (i) Continuous (able to operate for very long periods of time as long as enough polymer is supplied), (ii) Batch or semi-continuous (able to make one material at a time, or possibly operate in a cyclic or fashion for a long time with small breaks between processing) THERMAL EXTRUSION CASTING TO FORM A THERMOSET POLYMER BLOW MOLDING MELT SPINNING OF FIBERS THERMOFORMING - INJECTION MOLDING - BLOW EXTRUSION - CALENDERING - COMPOUNDING - ROTATIONAL MOLDING 17.6. You work at a plant that makes poly(ethylene terephthalate), PET, bottles using blow molding, but the production line is having a problem with lots of rejected bottles, which must be ground up and recycled. The rejected bottles sometimes have holes in the threaded part at the top of the bottle (where the screw-cap goes), or this part is often too thin and not rigid enough for the screw cap to fit snugly.

Using the above data, deduce the rate law, the integrated rate law, and the value of the rate constant, all in terms of pressure units in atm and time in seconds. Predict the pressure of C2H5OH after 900. s from the start of the reaction. (Hint: To determine the order of the reaction with respect to C2H5OH, compare how the pressure of C2H5OHdecreases with each time listing.)arrow_forward5.
