Briefly explain why small-angle grain boundaries are not as effective in interfering with the slip process as are high-angle grain boundaries with the help of diagrams?

Compared to High angle, relatively less presence of Crystallographic misalignment in grain boundary for small angle is reason behind its less effectiveness in interfering with slip process

Explanation:

Because of relatively much less presence of crystallographic misalignment in grain boundary for small angle, small grain boundaries are not as effective in compare to high angle in interfering with slip process

Less crystallographic misalignment in grain boundary causes not much change in slip direction and therefore interference to slip process is minimal.

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
