What reading level is Marine Boiler Management And Construction Being a Treatise On Boiler Troubles a book?
To quickly assess the difficulty of the text, read a short excerpt:
Irregular dark patches of pearlite will have made their appearance, which should be studied, and the sample should, if desired, be repeatedly etched until fine hair lines, the boundaries between the ferrite nodules, appear. Oval and long dove-coloured patches may also appear ; they are sulphide of manganese.
A 1/ solution of nitric acid produces nearly the same effect as picric acid, but is said to develop the crystalline structure of the ferrite.
A weak solution of iodine in water is sometimes... used ; it does not attack cementite, or, at least, it leaves it bright, but pearlite is darkened. This fluid is very troublesome.
An 8/ of copper sulphate of ammonia is very effective. The section is at first covered with copper ; this will wash off unless a wrong percentage has been used, and then certain portions of the ferrite which contain much phosphorus will appear in a brownish colour. Segregations are thus clearly revealed. If the sample before polishing has been severely strained, this etching fluid will also darken the strained regions, which are said to show slip bands.
