    FeTiP or Fe(Ti+Nb)P precipitates were observed in each sample, while much more incidence was that of the precipitates with niobium as without it. Precipitates without niobium FeTiP were observed only in 5 samples, in a ratio of 8:1,the Fe(Ti+Nb)P being the one with greater values. Oval shapes of Fe(Ti+Nb)P were observed after recrystallization annealing at the grain bounadries and also inside the grain itself. At the grain boundary in the sample with a lower coiling temperature of 565 °C was…

    Task 1 and 2 First ionisation energy – The first ionisation energy is the energy required to remove the most loosely held electron from one mole of gaseous atoms to produce one mole of gaseous ions each with a charge of +1. The first ionisation decreases as you go down a group. This is because the electrons are getting further away from the nucleus meaning it is easier to remove the outer electron. There is also less shielding thus allowing the outer electron to be removed much more easily. As…
