Introduction to Problem Solving Skills. What is Problem Solving and Why is it Important? The ability to solve problems is a basic life skill and is essential to our day-to-day lives, at home, at school, and at work. We solve problems every day without really thinking about how we solve them.
Nitronium tetrafluoroborate is an inorganic compound with formula NOBF. It is a salt of nitronium cation and tetrafluoroborate anion. It is a colorless crystalline solid, which reacts with water to form the corrosive acids HF and HNO.
cluded that the presence of boron in steel can be effective up to 0.0030%. This is due to that boron is an interstitial element and has a very low solubility in Î±-solid solution (<0.003%) [1]. In order to raise the efficiency of the ac- tion of boron on the hardness of steel it is necessary to add titanium, which possesses a higher affinity for nitro- gen than boron and also forms nitrides in liquid phase. So, sufficient Ti was added to combine with the nitrogen to forming TiN. Therefore, in steel containing 0.0055% B, the titanium content is not sufficient to combine with nitrogen.
