Description

The data presented is an abridged version of that provided in a paper by Kotecki and Ogborn [1] which presented the effect of low stress abrasion resistance as a function of composition and hardness of hardfacing alloys. It was necessary to remove a number of lines in the database as they were required to be complete for the purpose of neural network analysis - some lines in the original paper contained omissions which the neural net could not comprehend.

The file hardface.tar contains two files: hardface.info is an ASCII text version of this document; hardface.dat contains the data.

Data in hardface.dat are arranged in 24 columns as follows :-

Columns 1-3 Binary representation of welding method used :-

Column 1 SAW - Submerged Arc Welding
Column 2 FCAW - Flux-Cored Arc Welding
Column 3 SMAW - Shielded Metal Arc Welding

for example :-

1 0 0 - represents SAW
0 0 1 - represents SMAW

Column 4 Number of deposited Layers.

Column 5 Hardness (Rockwell C).

Column 6 Carbon (wt%).

Column 7 Manganese (wt%).

Column 8 Silicon (wt%).

Column 9 Chromium (wt%).

Column 10 Molybdenum (wt%).

Column 11 Vanadium (wt%).

Column 12 Niobium (wt%).

Column 13 Tungsten (wt%).

Column 14 Nickel (wt%).

Column 15 Aluminium (wt%).

Column 16 Average weight loss (g).

Columns 17-23 Binary representation of microstructural types observed :-

Col.	Code	Microstructure
17	FB	Ferrite/bainite
18	MS	Martensite
19	NE	Near-eutectic austenite-carbide
20	PC	Primary carbides with austenite-carbide eutectic
21	PA	Primary austenite with eutectic austenite-carbide
22	AM	Austenitic manganese
23	MA	Martensite and austenite mixed

Column 24 Identification Label - corresponds to column 1 in [1].
