2) What is the need for alloying?
please answer my question...and please don't give idiot answer...​

Answer 1

Answer:

1. Bacterial growth is affected by temperature. ... Below the minimum temperature bacterial growth becomes inactive but does not kill the organism. However, if the temperature is raised above the maximum, bacteria are soon killed. Most cells die after exposure to heat treatments in the order of 70°C for 15 seconds.
2. Alloy formation increases the tensile strength of the parent metal. Enhance corrosion resistance: Alloys are more resistant to corrosion than pure metals. Metals in pure form are chemically reactive and can be easily corroded by the surrounding atmospheric gases and moisture.
