The Mean

Preparation of nanocrystalline 430L stainless steel powders by high-energy ball milling has been investigated. The samples were characterized by scanning electron microscope (SEM), X-ray Diffraction (XRD) and Matersizer. The SEM observation confirmed that the cold welding and fragmentation behaviors occurred during high-energy ball milling, which has important effect on the changes of the particle size. In the initial stage (0-10h), particle size increased and crystalline grain size decreased evidently. The mean particle size got to 330μm and the crystalline grain size got to 23nm for sample of 10h ball milling. In the later stage, the particle size decreased and the refinement of crystalline grain became difficult. The crystalline grain size of sample for 50h ball milling only got to 15nm.

Arang daun bambu tutul sebagai kajian produk nanopartikel dan penghasil silica yang memiliki berbagai keunggulan dari segi sifat fisika dan kimia. Pada penelitian ini produksi nanopartikel menggunakan High Energy Milling (HEM) tipeshaker mill untuk memproduksi nanopartikel dari arang daun bambu tutul. Pada penelitian ini dilakukan uji PSA untuk menganalisa ukuran partikel, untuk menganalisa distribusi morfologi partikel dan komposisi kimia yang terkandung dalam material menggunakan uji SEM dan EDX. Siklus yang digunakan pada penelitian adalah 2 juta siklus dengan putaran motor listrik 1000 rpm, dan diameter bola baja 1/4 inchi. Tabung stainless steel berjumlah 4 dengan diameter tabung 2 inchi dan tinggi tabung 120 mm dengan perbandingan volume ruang kosong tabung yaitu 1:1, 1:2, 1:3, dan 1:4 dengan material. Penelitian ini bertujuan untuk mengetahui pengaruh volume ruang kosong tabung dan rata – rata diameter partikel, distribusi partikel, dan komposisi yang terkandung dalam partikel hasil tumbukan dengan alat shaker mill. Hasil penelitian ini menunjukkan bahwa volume ruang kosong tabung sangat berpengaruh pada mekanisme tumbukan. Dari uji PSA semakin besar volume ruang kosong tabung, semakin kecil ukuran partikel material yang dihasilkan. Hasil uji SEM dan EDX didapatkan unsur kimia karbon yang paling tinggi 68,47 % pada volume 1:1 ruang kosong tabung. Sehingga arang daun bambu tutul merupakan sumber potensi sebagai penghasil silica.

High Nitrogen Stainless Steel

High nitrogen nanostructured Fe-17Cr-11Mn-3Mo stainless steel powders were produced by high energy ball milling under a nitrogen atmosphere. It was found with increasing the milling time, the nitrogen contents of the powder mixtures increase linearly up to 1.98 wt pct after 96h, and a linear regression equation, WN = 0.19357 + 0.01887t , has been further established. In addition, with the increased milling time, the crystallite sizes and particle sizes of the powders decrease continuously, the lattice strains and sphericity of the powders increase gradually. After milling 60h, the high nitrogen nanocrystalline stainless steel powders with a fine particle size range of 5~10μm, excellent sphericity and uniform components can be obtained, whose crystallite size is about 5.0nm and lattice strain is about 1.0%. The powders milled for 60h was compacted using spark plasma sintering process at different temperatures. It is found that a fully austenitic high nitrogen stainless steel with almost full densification can be obtained by SPS at 1000°C, whose nitrogen content is 0.82 wt pct.
