update on laser sintering project

We spoke to Professor Milan Brant on Monday at IRIS at Hawthron. He explained that they were waiting for a technician to cut the sample slices off for our group. We mentioned to him a piece of mild steel with a pilon of stainless steel welded on top of it. He responded by saying we could get a simple shape, eg. a cube, of laser sintering material.

We offered to him to cut up the samples ourselves, polish them and test them accordingly, considering the lab at Swinburne has the equipment required to perform our tests.
Professor Brant told us he will contact us within the next few days.

I perosnally Don will be polishing and etching the samples slices. From that point on, i intend to perform a microscopic examination of the grain structure and any firement. I particularly would like to see if the interzones between laser welded strings.

I personally Ian will be performing hardness testing on the samples, from there i can examine the level of hardness in each sample. I would like to see what the sample looks like through the microscope n the structure on top of the sample.
